A spray granulation apparatus

Abstract

This utility model discloses a spray granulation device, belonging to the technical field of spray granulation devices. It includes an output pipe, a device body, and a sealing ring. The output end of the pump is connected to the output pipe, and a nozzle is movably mounted on the bottom end of the output pipe via a sealed bearing. Large holes are evenly distributed on the outer wall of the nozzle, and small holes are distributed on the outer wall of the nozzle on one side of the large holes. Baffles are installed on the outer sides of the large holes, and rotating sleeves are connected to both ends of the baffles. A screen is installed on the inner side of the screening box. This utility model utilizes the outward pulling of a pull plate, which deforms the first return spring, causing the movable rod to move the locking block away from the second locking hole.

Description

Technical Field

[0001] This utility model relates to the technical field of spray granulation devices, specifically a spray granulation device. Background Technology

[0002] Ferrite magnetic rings are components capable of suppressing electromagnetic interference. Manganese-zinc ferrites have excellent electromagnetic interference suppression capabilities. In electronic devices, high-frequency signals often generate unnecessary electromagnetic radiation, interfering with other electronic devices. Manganese-zinc ferrites can effectively absorb these high-frequency signals, reducing the generation of electromagnetic radiation and thus improving the anti-interference capability of electronic devices. The production of manganese-zinc ferrite cores requires a spray granulation device to granulate the product slurry. Existing spray granulation devices require changing the nozzle to adjust the nozzle size, making operation more cumbersome. Furthermore, spray granulation devices do not have an efficient screening structure, thus failing to screen out particles of uniform size. In view of these issues, in-depth research was conducted, leading to this case. Utility Model Content

[0003] The purpose of this invention is to provide a spray granulation device to solve the problem mentioned in the background art that the existing spray granulation device does not have the advantages of easy adjustment of granulation size and efficient screening structure.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a spray granulation device, comprising an output pipe, a device body, and a sealing ring. A control panel is installed on the outer wall of one side of the device body. A slurry tank is installed on one side of the top of the device body, and a pump is connected to one side of the slurry tank. The output end of the pump is connected to an output pipe, and a nozzle is movably mounted on the bottom end of the output pipe via a sealed bearing. Large holes are evenly distributed on the outer wall of the nozzle, and small holes are distributed on the outer wall of the nozzle on the side with the large holes. Baffles are installed on the outer side of each of the large holes. Both ends of the baffle are connected to rotating sleeves, and the inner walls of the baffles are equipped with sealing rings. The outer wall of the nozzle at one end of the rotating sleeve is provided with a second locking hole, and the outer wall of the nozzle on the side of the second locking hole is provided with a first locking hole. A filter screen is installed below the nozzle. A fan is installed on the outer side of the device body below the control panel, and a heating tube is installed on one side of the fan. A discharge pipe is connected to the other side of the device body, and a screening box is connected to one side of the discharge pipe. A screen is installed inside the screening box, and a hopper is connected to one side of the screening box.

[0005] Preferably, a first drive motor is installed on the inner wall above the device body, and the output end of the first drive motor is connected to a drive gear through a drive shaft. A driven gear is installed on the outer wall above the nozzle, and a meshing transmission structure is formed between the driven gear and the drive gear.

[0006] Preferably, the outer walls at both ends of the nozzle are provided with limiting grooves, and the inner walls of the rotating sleeve are movably connected to the limiting grooves via limiting wheels.

[0007] Preferably, a first return spring is installed on the outer wall of the rotating sleeve at both ends of the baffle, and a movable rod is movably installed on the inner side of the first return spring. A pull plate is connected between one end of the movable rod, and a locking block that cooperates with the second locking hole is connected to the other end of the movable rod.

[0008] Preferably, a fixing pipe is installed below the filter screen, and an air outlet pipe is evenly connected to the top of the fixing pipe.

[0009] Preferably, dampers are installed at both ends of one side of the screen, and a second return spring is installed on the outer wall of one end of each damper.

[0010] Preferably, a tamping rod is installed on one side of the screen, a second drive motor is installed on the outer wall of one side of the screening box, and the output end of the second drive motor is connected to a turntable through a drive shaft. A connecting rod is movably installed on the outer wall of one end of the turntable, and one end of the connecting rod is movably connected to the tamping rod through a rotating shaft.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] This utility model provides a pull plate, a first return spring, and a large hole. By pulling the pull plate outward, the first return spring is deformed, causing the movable rod to move the locking block away from the second locking hole. Then, the operator rotates the rotating sleeve, causing the baffle to move to block the small hole. After the pull plate is released, the first return spring returns to its original position, causing the locking block to lock into the first locking hole. This allows for switching between the large and small holes without changing the nozzle, producing material particles of different sizes, thus solving the problem of inconvenient adjustment of granulation size.

[0013] This utility model provides a second drive motor, a tamping rod, and a screen. After material particles enter the screening box, they pass downwards through the screen for sieving. The second drive motor rotates a turntable, which in turn causes one end of a connecting rod to move in a circular motion. This causes the connecting rod to move the tamping rod left and right in a cyclical motion. As the tamping rod moves to the left, it presses against the screen, stretching and deforming the second return spring and damper. After the tamping rod moves away from one end of the screen, the second return spring and damper reset, causing the screen to return to the right. This left-right swaying motion of the screen solves the problem of lacking an efficient sieving structure. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example 1: Please refer to Figures 1-6A spray granulation device includes an output pipe 6, a device body 11, and a sealing ring 25. A control panel 12 is installed on the outer wall of one side of the device body 11. A slurry tank 10 is installed on one side of the top of the device body 11, and a pump 8 is connected to one side of the slurry tank 10. The output end of the pump 8 is connected to the output pipe 6, and a nozzle 4 is movably installed at the bottom end of the output pipe 6 through a sealing bearing. Large holes 22 are evenly arranged on the outer wall of the nozzle 4, and small holes 20 are arranged on the outer wall of the nozzle 4 on one side of the large holes 22. Baffles 21 are installed on the outer side of the large holes 22, and both ends of the baffles 21 are connected to a rotating... The inner walls of the rotating sleeve 19 and the baffle 21 are equipped with sealing rings 25. The outer wall of the nozzle 4 at one end of the rotating sleeve 19 is provided with a second locking hole 29, and the outer wall of the nozzle 4 on one side of the second locking hole 29 is provided with a first locking hole 23. A filter screen 16 is installed below the nozzle 4. A fan 14 is installed on the outside of the device body 11 below the control panel 12, and a heating pipe 13 is installed on one side of the fan 14. The other side of the device body 11 is connected to the discharge pipe 3, and one side of the discharge pipe 3 is connected to the screening box 2. A screen 18 is installed on the inside of the screening box 2, and a feeding hopper 1 is connected to one side of the screening box 2.

[0023] A first drive motor 7 is installed on the inner wall above the device body 11, and the output end of the first drive motor 7 is connected to the drive gear 9 through the drive shaft. A driven gear 5 is installed on the outer wall above the nozzle 4, and a meshing transmission structure is formed between the driven gear 5 and the drive gear 9.

[0024] The outer walls at both ends of the nozzle 4 are provided with limit grooves, and the inner walls of the rotating sleeve 19 are movably connected to the limit grooves through limit wheels;

[0025] The outer walls of the rotating sleeves 19 at both ends of the baffle 21 are each equipped with a first return spring 26, and the inner side of the first return spring 26 is movably equipped with a movable rod 27. A pull plate 24 is connected between one end of the movable rod 27, and a locking block 28 that cooperates with the second lock hole 29 is connected to the other end of the movable rod 27.

[0026] Specifically, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, when using this structure, by pulling the pull plate 24 outward, the first return spring 26 is pulled and deformed, causing the movable rod 27 to move the locking block 28 away from the second locking hole 29. Then, the operator rotates the rotating sleeve 19, causing the baffle 21 to move simultaneously to block the small hole 20. After releasing the pull plate 24, the first return spring 26 returns to its original position, causing the locking block 28 to lock into the first locking hole 23. This allows for switching between the large hole 22 and the small hole 20 without changing the nozzle 4, thus producing material particles of different sizes.

[0027] Example 2: A fixing pipe 15 is installed below the filter screen 16, and an air outlet pipe 17 is evenly connected to the top of the fixing pipe 15.

[0028] Both ends of one side of the screen 18 are equipped with dampers 35, and a second return spring 34 is installed on the outer wall of one end of the damper 35.

[0029] A tamping rod 30 is installed on one side of the screen 18, and a second drive motor 33 is installed on the outer wall of one side of the screening box 2. The output end of the second drive motor 33 is connected to a turntable 32 through a drive shaft. A connecting rod 31 is movably installed on the outer wall of one end of the turntable 32, and one end of the connecting rod 31 is movably connected to the tamping rod 30 through a rotating shaft.

[0030] Specifically, such as Figure 1 , Figure 5 and Figure 6 As shown, when using this structure, after the material particles enter the screening box 2, they are screened downwards through the screen 18. The second drive motor 33 operates to rotate the turntable 32, which causes one end of the connecting rod 31 to move in a circle. The connecting rod 31 drives the tamping rod 30 to move left and right in a circular motion. As the tamping rod 30 moves to the left, it squeezes the screen 18. The second return spring 34 and the damper 35 are stretched and deformed. After the tamping rod 30 moves away from one end of the screen 18, the second return spring 34 and the damper 35 return to their original positions, causing the screen 18 to return to its original position to the right. This causes the screen 18 to move left and right and shake, achieving efficient screening.

[0031] Working principle: When using this device, the pump 8 first draws the slurry from the slurry tank 10. The slurry is sprayed downwards as mist beads through the nozzle 4. The heating pipe 13 and the fan 14 work to form hot air. The hot air enters the fixed pipe 15 and is then sprayed upwards through multiple air outlet pipes 17. It is filtered through the filter screen 16. The hot air quickly dries the mist beads into granules. After granulation, the material enters the screening box 2 through the discharge pipe 3.

[0032] Implementation steps for the first innovation point:

[0033] Step 1: By pulling the pull plate 24 outward, the first return spring 26 is pulled and deformed, causing the movable rod 27 to move the locking block 28 away from the second lock hole 29 at the same time. Then, the operator rotates the rotating sleeve 19, causing the baffle 21 to move to block the small hole 20 at the same time.

[0034] Step 2: After releasing the pull plate 24, the first return spring 26 returns to its original position, causing the locking block 28 to engage in the first locking hole 23 and lock, which facilitates switching between the large hole 22 and the small hole 20 without replacing the nozzle 4, thus producing material particles of different sizes.

[0035] Implementation steps for the second innovation point:

[0036] Step 1: After the material particles enter the screening box 2, they are screened downward through the screen 18. Particles that meet the size requirements are discharged downward through the screen 18, while particles that do not meet the size requirements are discharged through the feed hopper 1.

[0037] Step 2: The second drive motor 33 operates to rotate the turntable 32, which in turn causes one end of the connecting rod 31 to move in a circle. This causes the connecting rod 31 to drive the tamping rod 30 to move left and right in a circular motion. As the tamping rod 30 moves to the left, it squeezes the screen 18. The second return spring 34 and the damper 35 are stretched and deformed. After the tamping rod 30 moves away from one end of the screen 18, the second return spring 34 and the damper 35 return to their original positions, causing the screen 18 to return to its original position to the right. This causes the screen 18 to move left and right and sway, achieving efficient screening.
